Covariates include gender (except in MZ comparisons), waist circumference, and history of hypertension. MZ: monozygotic; DZ: dizygotic. , , and refer to Montreal Neurological Institute voxel coordinates; regions are based on the Talairach Daemon; : peak voxel cluster; L: left hemisphere. All comparisons are within twin pairs and corrected for family-wise error (FWE) threshold of 0.05.
